Show 542 MR. W. A. FORBES ON ANTILOCAPRA AMERICANA. [Nov. 16, horns, drawn of half the natural size, so far as the movements of the animal allow this to be done. The base of ^ . * ^ « * » ™J horn is thicker and larger than the top part, and is of a diffeient texture beina: erever and pretty thickly covered with long whitish, 9 - W ^ L S S n . The integument is rather soft and decidedly warm to the touch; and growth is evidently going on here at a rapid pace. The top part, about one inch long, is smoother and blacker, though nearly white at the tip. It is nearly glabrous, with only a very few small hairs, and has the appearance and touch of ordinary horn. It is separated from the basal ' pedicel part by a slight constriction, and is movable on this part in a slight degree from side to side. Fig. 3. Horn of Prongbuck, one month after the shedding of the old horns: ^ nat. size. " Fig. 3 shows the condition of the horns today (November 16), exactly four weeks after the shedding took place. As will be seen, the horns have grown rapidly, and have already acquired a characteristic inward curve. The hair-covered ' pedicel' and the black apical part still retain their original character unaltered; and all the increase of length in the horn is due, as far as I can make ont, to the lengthening-out of the * node ' (to use a botanical term), which is marked off as a slight constriction on the fresh horn (vide fig. 2). |
